Baseline Technical Report <br /> ARCADES Report for Soils and Biological <br /> Resources, MLE2 Project Area <br /> owned by CC&V surrounding the Cresson mine. The legal description of the project <br /> area is: <br /> • Township 15 South, Range 69 West, Sections 16 to 21 and 29 <br /> • Township 15 South, Range 70 West, Sections 24, 25, and 36 <br /> The project area ranges in elevation from approximately 9,000 feet (2,743 meters) to <br /> 10,500 feet (3,200 meters) above mean sea level (amsl). Vegetation communities <br /> are relatively diverse consisting of communities such as grasslands, woodlands, and <br /> wet meadows. Geology in the District consists of an Oligocene-aged (approximately <br /> 30 million years ago) diatreme-volcanic, intrusive complex surrounded by <br /> Precambrian rocks. The eastern portion of the District is characterized by a flat-lying <br /> sequence of volcanoclastic sediments and phonolite flow units. The central portion of <br /> the District is dominated by complex flow dome structures with cross-cutting intrusive <br /> dikes and sills. The western side of the District contains extensive areas of diatremal <br /> volcanoclastic breccias with scattered intrusive and flow dome features (Vardiman et <br /> al. 2006). <br /> 1.2 Survey Methods <br /> 1.2.1 Phase I—Compile Existing Data <br /> ARCADIS performed a detailed compilation of existing resource information available <br /> for the MLE2 project area (hereafter referred to as the 'survey area'). The survey <br /> area is part of the larger Cresson Project area that encompasses most of the District <br /> (Figure 1-1). Based on the information required by the CMLRB and Teller County for <br /> the permit amendment, information on the following resources was compiled: <br /> • Soil resources, including plant growth medium; <br /> • Vegetation resources; <br /> • Wildlife resources; and <br /> • Special status species (Threatened, Endangered, Sensitive and Candidate <br /> Species [TECS] and Colorado sensitive wildlife and plant species). <br /> 1.2.1.1 Soil Resources <br /> Previous soil surveys were conducted within the Cresson Project area by Nerco <br /> Minerals Company in 1984 and by Newport Minerals in 1985. These surveys were <br /> conducted in the northern portion of the District. Preliminary soil mapping was <br /> CCV Baseline Soils Biology Resource Report(11-17-11)doc 2 <br />
